The RECOM certified PSU used in the wireless SwitchMotes was a pretty expensive part of the kit. This was sourced from Digikey/Mouser and used to cost around ~$11 in volume. There is now a new PSU with identical size and pinout, very similar specs but even more certifications, weighs less, lower noise, same Austrian quality. The really great part? It costs just ~$6.50 making the SwitchMote kits price go down!
